Brown, who still lives in the home she shared with her late mom in Atlanta, also told Winfrey she's "doing as good as I possibly can" and that she still feels Houston's presence.

"I feel her pass through me all the time. I wake up at night," said Brown, who turned 19 less than a month after her mom died. "She would say at 5 a.m. the saints start praying. I wake up now and look at the clock and it's 5 o'clock. I start praying."

Brown said her mom even continues to joke with her.

"Lights turn on and off (in the house) and I'm like, 'Mom, what are you doing?'" Brown said. "I can still laugh with her and still talk to her."
